Analysis The results that I have collected have proved very conclusive. From the graphs that have been plotted I have been able to deduce that when a spring is added to the spring in series then the extension increases proportionally, as is proved below: Force (N) Single spring (m) Spring in series (m) 0 0.000 0.000 1 0.044 0.086 2 0.087 0.157 3 0.130 0.234 4 0.173 1.312 5 0.216 0.399 6 0.258 0.481 7 0.278 0.553 8 0.336 0.652 When the load 1N is added to the springs in series the extension is 0.086 m, however when the load is added to the spring on it's own the extension is only 0.044 m. This proves that the equation k = f / x is true. This is because when the load is kept the same but the spring stiffness is doubled then the extension is also doubled. To work out the spring constant I will need to use the equation: K = Force or Load / gradient The spring stiffness is a measure as to how much the string is extended when...
